ABRAHAM BRINKHUIS, OF HOSPERS, IOWA.

Wanner-I.

Application filed January 5, 1915.

To all whom it may concern.

Be it known that I, A RA AM BRINK- HUIS, a citizen of the United States,and resident of Hospers, in the county of Sioux and State of Iowa, haveinvented a new and useful Wrench, of which the following is aspecification.

The object of my invention is to provide a wrench of simple, durable andineXpen sive construction, particularly adapted for installing orremoving horseshoe calks of the removable type, but also adapted for avariety of other uses.

A further object is to provide a wrench of the type mentioned, adaptedto receive the call: and after a slight rotation firmly grip the calkfor screwing it into or out of the horseshoe.

A further object is to provide a device of the general type mentioned togrip a calk or other movable member for rotating it in either direction.

My invention consists in the construction, combination and arrangementof the various parts of the device, whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings, in which:

Figure 1 shows a top or plan View of a wrench embodying my invention.

Fig. 2 shows an inverted plan view of the same.

Fig. 3 shows a vertical, sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 shows a view similar to that shown in Fig. 2 of a part of thewrench, the call: being shown in section, taken on the line 44 of Fig.3.

In the accompanying drawings I have used the reference numeral 10 toindicate generally the handles of my improved wrench. The centralportion 11, which connects the handles 10, is widened out and is flat,as shown in the drawings. The flat portion 11 is provided with anangular opening 12, which receives the angular end 14 of the member 15,the body of which is cylindrical. The end 14 is held in the opening 12by a set screw 13.

Formed on the lower end of the member 15 is a jaw or gripping member 16,which is approximately elliptical in general plan outline, but isprovided with serrations or teeth 17 and 18 on the side edges of itstransverse median. line. The teeth 17 and Specification of LettersPatent.

18 are inclined in different directions, as

shown in Figs. 2 and 4.

Rotatably mounted upon the body 15 is a sleeve 19, formed on the lowerend of which is a jaw or gripping member 20, which is mounted off centeron the member 19. The lower surface of the member 20 is practically on alevel with the lower surface of the jaw or gripping member 16. Offcenter with relation to the member 15, the member 20 is provided with anopening 22 extending through-it, which may or may not be tapered fromits lower to its upper end, as shown in Fig. 3, to fit the calk 28 to bemounted in the horseshoe 24. The member 20 is formed with a portion ofits lower surface cut away at 26. The cut away portion 26 extendsthrough the opening 22 to the side of the member 20. The gripping device16 is received within said cut away portion 26, and when the sleeve 19and the portion 20 are turned to one position. of their movement, theend of the gripping device 16 enters the opening 22, while when inanother position of the parts the gripping device 16 is spaced away fromthe opening 22. The member 16 may be of any desired width for grippingcalks of different sizes. The member 15 may, if desired, be set a littleto one side from the line 33 (Fig. 2) if desired for certain purposes.

The walls 21 of the portion 20 adjacent to the cut away portion 26, arecurved or cam faced, as shown in Fig. 4.

lVhen it is desired to grip the calk 23 the parts 19 and 20 are turnedto position where the gripping member 16 is spaced from the opening 22,and the whole wrench is lowered over the calk 23 until the calk isreceived within the opening 22. The wrench is pressed downwardly untilthe walls of the opening 22 frictionally engage the calk. The wrench isthen turned by means of the handles, whereupon the teeth of the gripping device 16 will engage the calk, as shown in Fig. 4, and a continuedrotation of the wrench will screw the calk into the horseshoe 24.

Rotation of the wrench in the opposite direction will unscrew the calk.

It will readily be seen that the device may be used with calks differingsomewhat in size, and the only difference in operation will be that theteeth of the ripping device 16 will. engage the calk a little earlier orlater in the rotation of the wrench, depending upon the size of thecalk.

It is Well-known that calks of this type are usually provided withangular portions at their bases for receiving a wrench, but that suchportions are usually not satisfao tory insomuch as the wrench works themoff and thereafter will not properly grip them.

In my improved wrench the calk can be quickly and easily gripped androtated as often as may be desired for properly in stalling it in ahorse-shoe, or removing it therefrom.

In this connection it should be mentioned that with a very slightvariation in the" size of the opening 22 my improved wrench may 7 beadapted for a variety of uses.

It will be understood that some changes may be made in the details ofthe construction of my improved device without departing from itsessential features and purposes, and it is my intent to cover by thisapplication any such changes which may be included within the scope ofmy claims.

I claim as my invention:

1. In a wrench, a sleeve having a pair of adjacent parallel openingstherethrough and a substantially circular depression sur rounding oneend of one of the openings, said depression being of suflicient diameterto intersect the periphery of the other opening, a shank rotatablymounted in the opening having the depression surrounding it andprojecting from the sleeve at the end opposite such depression, and agripping member fixed to the other end of the shank within suchdepression, said gripping member being substantially equal in length tothe diameter of the depression, and in width to the diameter of theopening wherein the shank is mounted.

2. In a wrench, a sleeve having a pair of adjacent parallel openingstherethrough and a substantially circular depression surrounding one endof one of the openings, said depression being of suflicient diameter tointersect the periphery of the other opening, a shank rotatably mountedin the opening having the depression surrounding it and projecting fromthe sleeve at the end opposite such depression, and a gripping memberfixed to the other end of the shank within such depression, saidgripping member being substantially equal in length to the diameter ofthe depression, and in width to the diameter of the opening wherein theshank is mounted, the longer edges of the gripping member beingserrated, with the teeth pointing away from the transverse central line.
